Stranger Things - The Upside Down (Male OC x ST)

Summary:

The Harrison family moves from LA to Hawkins in the 1980s, hoping for a fresh start. Instead, they land right in the middle of a dimensional nightmare.

When a new rift tears open in the outskirts of town, the Upside Down doesn't just leak through-it begins colliding with reality. The air glitches. Shadows distort. Time loops. And five siblings become deeply entangled in something ancient waking on the other side. Jax, Raelynn, and Katie-three teens just trying to survive Hawkins High-get dragged into the chaos as the dimension targets their emotional weaknesses. Meanwhile Eli and Maya, the younger siblings, start experiencing strange psychic bleedthrough: visions, creatures in their dreams, and memories that aren't theirs.

As the Harrison kids cross paths with Hawkins' original misfit crew (Mike, El, Lucas, Dustin, Nancy, Max, and the rest) they discover the truth: This rift isn't like the one that took Will. This one is alive-thinking, choosing, evolving. Two worlds are merging. And someone in the Harrison family is the key to whether Hawkins survives...or gets rewritten forever.
